rlocus (MathScript RT Module Function)

Owning Class: dynchar

Requires: Control Design and Simulation Module and MathScript RT Module

Syntax

rlocus(SysInSISO)

[roots, gains] = rlocus(SysInSISO)

Description

Creates an Evans, or root-locus, plot of closed-loop poles of a single-input single-output (SISO) system model as the feedback gain increases from zero to infinity.

Examples

Inputs

Name Description
SysInSISO Specifies a linear time-invariant (LTI) SISO model in transfer function, zero-pole-gain, or state-space form.

Outputs

Name Description
roots Returns the locations of the closed-loop roots of the SysIn model. roots is a complex matrix.
gains Returns the gain values this function uses to create the root locus plot. gains is a real vector.

Details

The following table lists the support characteristics of this function.

Supported in the LabVIEW Run-Time Engine Yes (if you request output)
Supported on RT targets Yes (if you request output)
Suitable for bounded execution times on RT Not characterized

Examples

num = [1]
den = [1, 5, 6]
SysInSISO = tf(num, den)
rlocus(SysInSISO)
